TUCK MARKING ATTACHMENT FOR SEWlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 370,869, dated October 4, 1887.

Application filed April 25, 1885. Serial No. 163.381. (Modem To all whom it may concern.-

Be it known that I, J OSEPH R. HEBERT, a citizen of the United States, and a resident of Brooklyn, Kings county, in the State of New York, have invented a newand useful Improvement in Tucking Attachments. for Sewing-Machines, of which the following is a specification.

My invention consists in providing the point upon or by which the mark upon the material operated upon is to be made with aroughened or serrated surface.

Ihe object of this construction is to prevent undue slipping of the fabric, so apt to occur in practice when the point is smooth or without a roughened surface.

Referring to the drawings, Figure 1 represents a top view of a ruffling attachment containing my improvement; Fig. 2, an edge view; Fig.3, an end view showing the roughened point or marker.

In the drawings, A is the frame proper, to which all parts are connected which form the attachment proper; B, part of the adjustable frame; 0, another part of the adjustable frame, provided with a graduated scale; D, a leverarm for operating the device. through the medium of the needle-bar of the sewing-machine; E, a point upon the frame serving as a partial support for the rocking lever which operates the creaser; F, the roughened-surface point upon which the creasing-finger impinges. G is the gage against which the edge of the material to be operated upon is guided. II is a flexible spring tension or smoother adapted to press lightly upon the strip which is passed beneath while being operated upon. I is an adjusting-screw by which the several adjustable parts are held in a fixed position.

The operation of the attachment is the same as those of a similar combination too well known to require any explanation here. Heretofore it has been found a very difficult task to prevent the goods subjected to the tuckmarking process from slipping, or crawling, as it is sometimes termed, in such manner as to produce slight crooks, thereby varying the width of the marks or folds, which is very undesirable, particularly when very fine tucks are desired and where thin goods are used, and to the end that this difficulty might be avoided I have made the improvement hereinbefore described.

,It is obvious that my improvement may be applied to the marker of nearly every tuckmarking attachment provided with apoint or edge upon which a creasing-finger impinges. The said point or edge may be serrated or roughened by a knurling-tool, well known to mechanics, or by any other means that will produce the desired effect.

My improved tuck-marking attachment is operated in connection with the sewing-ma-' VVitne-sses:
